Description

The invention relates to the field of weapons technology and can be used in small arms equipped with a laser target designator (LCC).

The well-known Makarov pistol (PM) with a laser pointer, which consists of a body, a laser radiation unit, a cover with a protective glass and a power supply, fixed by a back cover with a wire and a power button, while the laser sensor is mounted on a dovetail-type rail installed on the frame of the gun with screws, and to install the bar, preparation of the surface of the frame is required, which ensures the fit of the bar and the implementation of three threaded holes for the screws securing the bar. After installation on the bracket, the LCC is fixed with two screws using a key. When replacing the power source, you need to disconnect the power key from the gun frame and unscrew the threaded back cover with wire. In case of incomplete disassembly of the pistol, the LCC must be removed.

Thus, this design of the LCC requires special revision of the gun when it is installed, and also increases the dimensions of the gun, which makes it impossible to use a standard holster and creates difficulties during operation (Weapons of modern infantry: an illustrated guide. Part I / S.L. Fedoseev - M. : LLC “Publishing House Astrel”: LLC “Publishing House ACT”, 2001, p.112).

The well-known revolver OTs-20, in which the LCC is used, is installed in a metal case, closed with lids on both sides. A cover with a protective glass protects the laser unit from damage and contamination. The front screw cover of the power supply is used to remove the power sources for recharging and replacement, and the back cover of the power supply is connected by a wire to the power button installed on the handle of the revolver in a special recess. The wire is closed with a protective cover. Thus, replacing the power source does not require disconnecting the power key with the wire from the frame of the revolver. The LCC is mounted on the frame of the revolver under the barrel using the dovetail joint and is fixed by tightening the screw.

The disadvantage of this design is that for disassembling the LTSU revolver, it is necessary to remove it, which creates difficulties in the operation of the revolver, as well as the inability to use the standard holster due to the increase in the dimensions of the revolver (J. “Arms”, 1997, No. 2, p.12 ; 2000, No. 1, p. 49).

Known gun with a laser designator according to US patent No. 5435091, class. F41G 1/34. The LCC of the known device comprises a power source, a laser module and a switch made in the form of a button installed in the handle.

The disadvantages of this invention is the inconvenience of turning on / off the LCC - in order to turn it on or off, you must press the switch button located on the handle, which creates inconvenience when shooting, affects its accuracy and unmasks the arrow, in addition, the placement of the laser target designator in the handle in this invention significantly increases the size of the handle and, therefore, reduces the convenience of using weapons.

The closest in technical essence and the achieved result is an invention in which a weapon with a laser pointer, containing a trigger, trigger pull, trigger, laser module, battery and switch, is additionally equipped with a slider and a pusher, which is connected to the slider at one end and the other - with a trigger or pull rod, and two holes are made on a slider, one for placing a switch in it when the trigger is not cocked, and the other for placing the switch with the cock cocked (patent 2141093 on the invention (RU), cl. F41G 1/34 from 29.09.1998).

The disadvantages of this technical solution is the difficulty of securing the target designator on the weapon, which consists in the need to disassemble the weapon and alter some of its parts using mechanical processing for this, while it is not possible to securely fix it on small-sized short-barreled weapons, in addition, fixing it on the handle increases the dimensions weapons, which makes it impossible to use a standard holster.

The present invention eliminates these disadvantages and solves the problem of simplifying the design, improving the operational characteristics of the gun and the possibility of using a standard holster.

To solve this problem, a gun with a laser target indicator (LCC), comprising a magazine with ammunition in the handle, containing a trigger, trigger pull, sear, trigger, laser module, battery and switch, differs in that the LCC consisting from a laser emitter, a battery, and an on / off button, mounted directly into the pistol grip pad, which also includes a tactical backlight LED, and the cold mode is used to turn on the LCC a straight pistol, in which, when the trigger protected by a trigger guard is pressed, a ball located in the housing opening and in contact with the rod on one side and the LOC power button on the other, exits the countersink in the rod and presses on the contacts, including the LOC, In this case, the power of the LCC and tactical illumination is carried out from two autonomous power sources.

According to this invention, for uniform illumination of space and getting rid of the shadow of the weapon body, tactical illumination can consist of two LEDs located one in each overlay, while the backlight is turned on by pressing a button on the pistol grip overlay and is blocked from being accidentally turned on while carrying a weapon, which it turns off when the weapon is removed from the fuse, and the tactical backlight is powered from a power source mounted in the pistol grip pad.

The invention is illustrated by the following drawings.

Figure 1. The layout of the LCC elements, tactical backlight LEDs and batteries in the gun handle.

Figure 2. The scheme of the gun and the relative position of the elements of the LCC, the tactical backlight LED and the batteries in the handle.

Figure 3. The scheme of the gun with the location of the tactical backlight LED and batteries in the handle.

Figure 4. Kinematic diagram of the inclusion of the LCC.

Figures 1 and 2 show the mutual arrangement of the LCC elements, the tactical illumination LED and the battery elements in the gun handle, including the laser radiation source (1), tactical illumination diode (2), the backlight ON button (3), the laser radiation source power cell ( 4), an overhead cheek of the gun handle (5), a button for turning on the laser source (6), a tactical illumination lock switch (7), spring-loaded contacts (8) going to the power source located in the opposite overlay (cheek) of the gun handle Practical backlight. And the relative position of the tactical backlight LED and the battery is shown in Fig.3.

A direct idea of the mechanical bonds of the inclusion of the LCC gives a kinematic scheme (figure 4).

LTSU is connected as follows. Pistols having a housing (frame) (10), a magazine with cartridges (11), which is located in the handle, contain a rod (leash) (12) in its design, which drives the pusher (sear) - not shown. This rod (leash) (12) has an idle speed when selecting idle while pressing the trigger of the gun. Since the trigger is protected by a trigger guard (frame), this eliminates the accidental inclusion of the LCC. When choosing idle, the ball (6) located in the opening of the housing (frame) and in contact with the rod (leash) on the one hand and the power button of the LCC (9) on the other, exits the countersink in the rod (leash) and presses on the contacts Buttons, closing them, turns on the LCU.

In the claimed invention solves the problem of simplifying bringing the LCC in working condition, it will always turn on before the shot is fired. Since the LCC is turned on only when the trigger is pressed, this saves the battery power, eliminates the need for additional protective devices to block the accidental inclusion of the LCC.

Tactical illumination is intended for use during firing. Its main purpose is to illuminate the target in low light conditions.

Tactical illumination is used to illuminate the target, as well as for temporary blinding and disorientation of the enemy. The tactical illumination in this invention consists of an LED and is located in the pistol grip (cheek), but it can consist of two LEDs located one in each grip, which gives uniform illumination of the space and eliminates the shadow of the weapon body. The backlight is turned on by pressing a button that is located on the cheek of the gun and has a lock from accidentally turning on while carrying a weapon, which turns off when the weapon is removed from the fuse or, if there is none, when the backlight lock switch is turned on, while avoiding the discharge of the battery LCC - tactical backlight is powered from an autonomous power source, which protects the LCC battery from accidental discharge when storing weapons with the fuse removed or with the toggle switch on locallockfile.

From literary sources it is known that a laser target designator (LEC) is designed to form on the target a light spot of a laser beam, combined with a mid-point of aiming.

The use of LCC allows even non-professionals to hit the target accurately. First of all, it is necessary to take into account that the laser pointer is an electric device, and for any electric device it needs to receive electric energy for its power using compact sources of electric current. Before using the LCC, it is necessary to install the batteries.

One of the main positive features of the laser designator is that it can significantly reduce the time between removing the weapon and the start of firing.

The main idea of using a laser for a target designator was that the light beam in a uniform air environment is direct and corresponds to the trajectory of the bullet at short and medium distances, depending on the ammunition. Thus, there is practically no need to use open sights, and firing can be carried out from the most uncomfortable positions, with sufficiently high efficiency. Inadequate illumination, poor shelter can affect the accuracy of firing using open sights, make their use even more impossible, and it is precisely in such situations that a focal plane is needed.

The most important point is the placement of the laser designator - built-in or those that are mounted directly on the gun. Built-in laser target designators - this phenomenon is quite rare at the present time, since the task of mounting it is difficult to solve. From literature sources, LCU modules with a battery are known that are built into the lining of the handle of the gun, which are turned on by a button that must be pressed to turn on the LCU, and this creates certain inconveniences when using it, and according to these sources, in these modules with the LCU the beam focuses lower and to the right aiming points and, in addition, it is indicated that a well-known sight with a laser sight is available for pistols of a certain brand - for example, Glock 17 and Colt 1911, that is, it is not universal.

In overall weapons samples, the LCC is mounted on seats that are either provided by the manufacturer or can be added by the owner of the weapon. On short-barreled weapons, it is traditional to locate the aircraft under the barrel, on the seat made in the frame of the weapon. You can meet laser target designators that are fixed on a safety bracket, on the shutter cover and even those that are screwed onto the barrel of the weapon or on the guide rod of the return spring when it is located under the barrel. All of the proposed laser designators have a current lead that connects the emitter to the on / off button. This current lead, passing outside the weapon casing, creates a great inconvenience when using the weapon in a combat situation, as it can be easily damaged, and this will lead to the failure of the entire LTC. The installation of the LCC on short-barreled weapons is almost always associated with contacting the weapons workshop. After installing the LTC requires shooting. All currently manufactured LOCs do not allow using them in the hidden carrying of weapons, since the LCC, significantly increasing the overall dimensions of the weapon, exclude the possibility of using holsters of hidden carrying.

Removable laser target indicators are produced for a wide variety of firearms and can be installed on virtually any model that has a seat for this device.

But removable target designators increase the dimensions of the weapon, and therefore the standard holster. Therefore, the formulation of the task of the device LCC in the handle of the gun, without increasing the size of the handle itself, is relevant.

The proposed LCC built-in to the handle is universal and can be used in standard pistols; it does not change the external dimensions of the weapon and allows using it for hidden carrying using standard holsters. The absence of an external conductor ensures stable and reliable operation of the LCC in combat conditions. The cover is quite accurately positioned on the pistol grip, as a result of which the factory setting of the LCC is enough for its further use and, as practice has shown, the need for further shooting of short-barreled weapons disappears.

The pad has mounting dimensions and fasteners that correspond to this type of weapon, therefore, the installation of this LCC can be carried out in the field using the usual standard tool included with the weapon.
